feature: List knots of opened ink file - in file browser

[blurymind]

A suggestion for a feature that could be a bit more involved is to give the user a list of the knots in the currently opened file

clicking on them could make ace editor scroll to their line

If you want to go even further - later on a search filter could be introduced

Duplicate of #23 - love the mockup
